Annie Morrison, creator of the Morrison Bone Prop, abandons the notion that language and thought are mainly processed in the left cerebral hemisphere, and coaches the actor to speak from the heart. Through this method, words acquire physical properties, such as weight, texture, colour and kinetic force. Think about Martin Luther King, Mao Zedong or Malala Yousafzai; potent speech impacts external events. And internally, it forms and shapes the world of the speaker. Seeing articulation as a purely mechanical skill is detrimental to an actor's process: it is crucial to understand what language is doing on a biological level. This workbook is invaluable for actors, both professional and in training, and also for voice and speech teachers.
